Is it possible for the compiler to automatically add a variable to a namespace?

Question

C++ / C#

Hello I have an empty namespace

namespace Addresses
    {
    }

But I would like to be able to add variables like
uintptr_t Addresses::myAdress = processManager.readMemory(GameAssembly);
that is, so that the compiler itself seems to create a variable in the namespace Addresses
This is not a dynamic allocation of variables, but ordinary variables

Answer 1

This is the only way in any language.

namespace Addresses {
  uintptr_t myAddresses = processManager.xxx;
}

Only in CPP file; in the header

namespace Addresses {
  extern uintptr_t myAddresses;
}

But I don't recommend it for two reasons.
1. Controlling delays during program initialization is a nasty thing. In all languages. For example, in Java ME I asked: do all long operations when something appears on the screen.
2. The second reason is specific to C++. The order of initialization of different modules is not defined. If the manager is in one module and the addresses are in another, the addresses can be initialized with a 50/50 chance when there is no manager yet.
